Google (GOOG) reportedly submitted a term sheet for Yahoo's (YHOO) ad tech business 3 months ago. It's added the offer didn't make it past corporate development, though talks remain ongoing. Multiple rumors have indicated Yahoo is looking to sell/outsource its ad tech business, and the media-focused Ross Levinsohn isn't expected to abandon this goal. IT services giants IBM and Accenture (ACN) have also been named as potential buyers.
